[1] Porcellio spinicornis is found in a variety of habitats across Europe, including forests, grasslands, and rocky areas.

[2] Porcellio spinicornis is a detritivore, feeding on a wide range of dead plant material, including leaves, twigs, and bark.

The use of the marsupium eliminates the need for an external water source for early development since it is filled with fluid from the mother isopod.

[4][5] Porcellio spinicornis has been introduced into the Isopod Hobby; however, few morphs have been isolated.
